Subject: linux-next: build failure after merge of the block tree

Hi Jens,

After merging the block tree, today's linux-next build (x86_64
allmodconfig) failed like this:

fs/ceph/rbd.c: In function 'rbd_rq_fn':
fs/ceph/rbd.c:1101: error: implicit declaration of function 'blk_fs_request'
fs/ceph/rbd.c:1101: error: implicit declaration of function 'blk_barrier_rq'

Caused by commit fc734ac98dbce1e3d3e1e1359524c279a336ac49 ("block: remove
wrappers for request type/flags") interacting with commit
e7fdb915217126d23ff2aafb2d5fdce21b763df1 ("ceph-rbd: rados block device")
from the ceph tree.

I applied the following merge fix patch (Christoph, I assume that this
should be directly applicable to the ceph tree, right?):
